There are so many reasons why a good cleaning contractor is so worth while engaging throughout the normal year.  We all have very busy lives and sometimes it is impossible to get all the cleaning jobs tackled when they are best tackled – like immediately anyone breathes in and out in the house!  If you have children and/or pets, the problem is doubled and trebled immediately.  The hair and muck that a pet produces is amazing for the size of the animal.  My daughter has a labrador – wonderful playmate and all round good sport, but by heck the amount of hair that he distributes in a weekend at mine, well it is breathtaking.  Then the grand children just have to start eating and a million bits of food and mess land on the carpets, furniture, under the furniture etc.  Cleaning professionally is the best way to keep on top of this – just a few times a year to have a deep clean.
